Yes, I know what you mean. But not necessarily so. The primary will be across AC Mains, so it will form a circuit, so some current will flow. The issue is how much. Check for Hum Caps, etc though.

Put the valves in one at a time, and measure the current every time.

If it's had a transformer change in the past, is the new transformer right. I think the problem is the transformer too, but check everything else first! Then find a transformer that will take the load (or an origional transformer) or get yours rewound.

Cheers,
